This invent-ion relates to display devices and is an improvement uponthe subject matter of copending applications Serial No. i

152,950 and Serial No. 157 ,372, iiled by me spectively.

An object of the present invention is to provide an electric displaydevice which may be detachahly secured to the shaft and` operated by themotor of an electric fan, so that the device may be used with a fan toprovide an attractive window or other display at the saine time the fanis used, or thev Jfan may be used without the device in the ordinarymanner.

Another object of the invention is the provision of an electric displaydevice which is used in connection withan electric fan of theoscillating type, the oscillating movement of the fan being utilized toactuate a switch for controlling the ow of current to the device,` sothat various pleasing and attractive effects may be obtained.

With the above and other objectsin view, the invention further includesthe following' novel features and details of construction, to behereinafter more fully described', illustrated inthe accompanyingdrawings and pointed out in the appended claims.

Figure 22 is a diagramillustrating the wir# ing arrangement. Referringto the drawings in detail wherein like characters of reference denoteycorresponding parts, the referencecharacter 25 28 of ysuitableconstruction.r The fan is ,pro-

vided with the usual guard 29.

The invention comprises a display devicev which may be made invaricusshapes and 7 ydesigns ,eone form of the device comprising`oppositely extending arms 30 which carryy electric lamps 31. Theselainpslmay be of any suitable size, kshape or color andany number ofarms may be provided for supporting the lamps with the'latt-erv arrangedin any desired position upon the arms. The f arms extend over .an`insulated hub 32 which n i carries Contact pins 33, conductoixwires 34Figure 2 is an enlarged fragmentary secconnecting these pins withthelamps 3l. The pins 33 extend beyond the face ofthe hub 32 and arereceivable within sockets .34 pro-.

vided in an insulating block 35, the latter being mounted upon the outerendof the shaft 26. Located withinthe sockets 34: kare contact members36 `which are electrically y connected `with collector rings 37mounted.

upon the shaft 26 and separated from one another byinsulators' 38.Conductor wires 39 which extend into theshaft 26 serve to provide meansof electrical connection` between the Contact members and the collector.

rings.` `Brushesll() engage the rings 37 and these brushes are connectedwith a suit-able source of current inthe ordinary manner.

rIt willbe seen v'that when-the devicegis mounted upon theend of themotor shaftk 26' andthe anis operated, current will be tween the contactpins 33 and the contact members 36, and to revent accidentaldisengagement of the display device from the shaft, there is provided ascrew 41 which extends through the hub 32 and engages the `nsulatingblock The device will thus Vbe held in position against the action ofcentrifugal torce, yet may be readily removed so that the fan may beused independently of the device.

As before stated, the display device may be of various forms. Forexample, it may be mounted upon lthe shaft 26 without the protection ofa guard such as is shown at 42 lin Figure 5 oit the drawings. In thisform of the invention, the device includes oppositely extending arms 43which project from the hubV 32 and which. carry ditlerent colored lamps31, the arms being designed to travel in the direction of the arrowshown in said ligure. The lamps will thus move in advance of the arms.

In Figure 6 the device is substantially the same in that it includesoppositely extending arms 43a which carry lamps 31 with the devicearranged in a guard 42a. Inaddit-ion, a reflector 44 is provided whichacts to increase the attractiveness of the device. Its most importantfeature however resides in the fact that the reflector may be used toreflect heat `from the lamps 31 which may be of suliicient power toprovide a relatively great amount of heat.

In Figure 7 the reflector 44a is substantially the Same diameter as thediameter of the guard 42. In this form of the invention, as in the formshown in Figure 6, the arms 43a travel in advance of the lamps incontradistinction to the form shown in Figure 5. Also, in the formillustrated in Figure 7 three lamps are carried by each arm instead oftwo.

In Figure 8, the arms 43b carry a number of small lamps 31, the lampsbeing differ ently colored and preferably of the type utilized forChristmas tree decoration. The arms 43b also serve to support reflectors44h, one reflector being carried by each arm.

In Figure 9, the device is similar to that shown in Figure 8, exceptthat the lamps 31b are diilerently spaced, the innermost lamp of one armbeing spaced a greater distance from the next adjacent lamp, than arethe remaining lamps, and the innermost lamp of the other arm is sospaced, that when the device is rotated, it will provide a circular pathof light within the space referred to.

In the form of the invention shown in Figure 10, four arms 43e extendfrom the hub 32. These arms carry dii'erently colored lights arranged inany suitable manner with the lights preferably of the type usuallyemployed in Christmas tree decoration. The

device is also preferably enclosed in a guard 42b and may be employedeither with or witliout a reflector.

In Figure 11 the display device includes cross arms 43d which carry adesired number of lamps of suitable type. The device is mounted within aguard 42 and the latter' serves to support. an annular member 45 whichCarries a circular row ot diderently colored lights 46.

A wiringdiagram of the device is shown in Figure 12 in which the lampsare connected by means of conductors with the collector rings 37, whilethe brushes 40. are con nected with a suitable source et currentindicated at B.

In Figure 13, the display device is mounted upon the sha 526 ot themotor attcr the manner previously described, the device which isindicated at I) may be of any desired type. The :tan shown in Figure 13is of the oscillating type and its standard 28 is adapted to havesecured thereto as shown at 47, a housing 48. This housing |encloses aswitch mechanism which comprises an insulating parti tion 49 suitablysecured within the housing. This partition forms a support forstationary contacts 50 which are connected by conductors 51 to brushes52 of the fan motor. These brushes engage collector rings 53 and one ofthese rings is connected by means of a conductor 54 with the lamps 55 ofone arm oi the display device. The other ring 53 is connected by aconductor 56 with the lamps 57 of the other arm of the display device. Ashaft 58 extends through the partition 49 and carries a contact disk 59.This disk is connected by means of a conductor 60 with a source ofcurrent B and the latter is connected by means of a conductor 61 with athird brush 62 which engages a collector ring 63. The ring 63 isconnected by a conductor 64 with the lamps 55. The disk 50 is providedwith an insulated portion 65 which may be either in the form of a cutout portion, or an insulated strip upon the disk. Secured upon the shaft58 is a ratchet wheel 66 whose teeth'are engaged by a spring actuatedholding dog 67. Mounted for free movement upon the shaft 58 is an arm 68which carries a spring actuated dog 69..v

When oscillating movement is imparted to the arm 68,'the dog 69V willmove the ratchet wheel 66 ina step by step movement. Movement isimparted to the arm 68 through a rod 70 which is connected as shown at71 to the housing 72 which contains the oscillating mechanism of thefan. This oscillating mechanism may be of any approved type and isoperatively connected with a bracket 72 in which the fan` shaft ismounted. y

It will be apparent from the foregoing description and accompanyingdrawings, that as the fan is operated, the display device D will berotated. In addition, the switch will be operated by the oscillatingmovement ofl thefan. This operation of the switch will rotate the disk59 so vthat when the contact members 50 arein the position illustratedby the dotted lines in Figure 19 of the drawings, the lights upon one ofthe crossed arms will be illuminated. When the contacts are in the po-Lsition shown in Figure 20 of the drawings7 the lamps upon only one-hallof one of the crossed .arms will be illuminated, and when the contacts50 are in the position shown in Figure 21 of the drawings, the lampsupon the other half of one of the crossed arms will be illuminated. Itwill thus be seen that full illumination of one of the crossed arms andhalf illumination of the other crossed arm will be alternately' eiected.By changing the number of contacts 50, a different arrangement ofillumination may be provided.

i It will be apparent from the foregoing description and accompanyingdrawings that the invention provides a display device which will providean attractive advertising medium for business purposes and may be usedupon the inside or outside of buildings. The invention will .alsoprovide an attractive and ornamental decoration for theaters as well asfor private homes.

It will be apparent that the fan motor may he provided with a resistanceswitch to control the speed of the motor, so that when the fan is used aproper speed may be maintained7 yand when the display device is used,the speed may be reduced as desired.

It is also to be understood that the reducing changes in its form,proportions and minor details of construction and the right is hereinreserved tomake such changes as properly fall within the scope of theappended claims. Having described the invention what is claimed is:
